FIRE-WALL CONSTRUCTION.

Application filed November 26, 1926; Serial No. 1 50 341;

This invention relates generally to improvements in fire walls, and 15 particularly directed to a header element for use in such face to loosely receive a metallicreinforcing element, adapted to engage the recess to prevent separation of the parts of the block in case'the block is broken. Features of the invention include the use of the block in a wall structure aswell as the block in G011} bination with the reinforcing element.

In the accompanying drawings forming a part of this specification Figure 1 is aperspective view of a wall construction using the improved blocks of this invention{ Figure 2 is a plan View of the block showing the reinforcing element therein;

Figure 3 is a transverse section of Figure 2; and i V Figure 4 is a detail perspective view of the metallic reinforcing element.

The wall illustratedherein is substantially ofthe type shown in my copending application above referred to. The metallic superstructure comprises an end post 1 and buckstay elements 2 extending longitudinally of the wall at the outer side. As in the application referred to, the header elements 3' are laid crosswise of the buckstays as shelf-forming headers, the shelf being formed at the inner side of the wall to receive the replaceable portion of the wall which is constructed of fire brick, generally of common form and size. The wall is laid in a manner similar to that set forth in the application above mentioned. v c

Each header element has a longitudinally arranged depression 5- therein, in this instance having the form of an elongated latseparation of the parts in a longitudinal direction in case the block is fractured, but also in a mannerito permit free expansion of the block in a longitudinal direction. a g In building the-wall, thereinforcing ele ments are simply dropped within the cavities or depressions formed in theupper face of the block. A loose lit is providedsothat the blocl; may freely expand and contract. T he upper surface of the bars, are below the level of-the upper surface of the headers, see Figure 3. V I v, p The block maybe used-in anyforin of wall, themain part of invention residing in the provision of a block of the naturedescribed, having a depression andhaving alreinforcing'element loosely arranged within the depression for the purpose set forth.

In ,order togcheapen the. wall ll insert an intermediate courseof header elements betweenthose which areHheldon, the metallic buckstays, These headers are of less length headers arearranged courseslO of firebricks laid asheaders and additional courses of bricks laid as stretchers are indicated at 11. These latter courses protect the front ends of the intermediate header elements. The illustration shows the upper part of the fire wall, but at the lower part the buckstay-supported headers generally extend only part way through the'wall and are protected at the lower portion of the wall in the same way that the intermediate headers are protected at the upper portion.

I claim as my invention 1,. A wall having a permanent portion comprising afplurality of superposed channel irons, extending lengtl'nvise of the wall,

rows of lire brick laid uponthe irons as headers and projecting at the inner side of the wall to form shelves, each header element having an I-shaped depression extending lengthwise and each header having an I- shaped bar loosely engaged in a corresponding I-shaped depression, and bricks filling the space between the headers and overlying the depressions.

2; A wall having a permanent portion comprising rows'of lire bricks laid as headersand supported by a masonry Wall, with the headers projecting at the inner side of the wallto form shelves each header having a longitudinally disposed depression in its up per face, and each having a har loosoly en-s gaged inthe' socket, the socket and bar being constructed for engagementto PI'GVGIIt'fSGPf-f" aration of the sections ofithe'bl-ock when thef same is broken, and bricks filling the space between the headers and coveringthe 'dQPJEQS" 'sions, some of said bricks forming a replaceable Wall portion. v t s. t V

3. A header having a longitudinally d sposed depression, anala bar en-gagediir the depre sion; the depression and ba'r' being co operative to {prevent se aratism ofi thdsc tionSJof-the header wh enthe headeris broken transversely.

gaging 'Wlth the corresponding portions of '"41;,-A ea er having a longitudi-n'a ens; posed depression, and a Thar; loosely; engaged in the depression; the, 'andhje; ,ing, cooperative to preVentseparationof the sections of the header: when"the 'heeder is t hegr'ooveto prevent'sepai'ationof the sec .i ti-onsof the block when broken transversely.

and a bar loosely disposed; within said groove:

and having portions engaging with the corbioken transversely. A, header element having a groove 1n one face side, whlch occupies a horizontal position theel ement is laid, said groove coniprisingua longitudinally extending portion and transversely arranged'portlons', and

a bar dispo'sed Within said groove andhavs ingtransv'ersely arranged portions engaging the correspondi-n portionsg of' the grooveto prevent longitn'dinalseparation of thesections of the block When broken -t-rans versely, one of the transverse portions lying I at that margin, which corresponds to the outer end of the header when laid;

8. A header element having a groove 11} position when the element is laid','said groove comprising a longitudinally extending For tion "and transversely arrangedportions, and a" harloo's el-y' disposed" Within said groove and having terminal portions engaging ivith the corresponding iiortions 'of the groove to prevent"separation of the sections of the block when broken transversely, (one of the transverse' portions lying at one margin of the block and the opposite transverse 'por tion lying adjacent theoppositegend' of the header.
